Abstract

The present invention provides a method of forming a flow restriction in a tube to be used as a capillary in a refrigeration system. The method includes providing at least one longitudinally disposed groove in the internal wall of the tube, shaping the tube longitudinally to a preselected configuration, and then squeezing a section of the tube while directing a fluid therethrough until the fluid reaches a preselected pressure.
